PROBLEM

1. OUTLINE OF DIAGNOSIS

Detect the malfunction of the intake air temperature sensor output properties. Using the following two diag-

noses, judge as NG when either is NG.

• Diagnosis 1 (correlation diagnosis): After the engine starts after the specified period of soaking time has

elapsed, diagnose by correlation between intake air temperature sensor value, engine coolant temperature

sensor value and ambient temperature sensor value. Judge as NG when the differences are both above the

specified value by comparing between intake air temperature and engine coolant temperature, intake air

temperature and ambient air temperature.

• Diagnosis 2 (stuck diagnosis): Judge as NG when intake air temperature does not change under the

driving condition where it should change, considering engine condition.

1. OUTLINE OF DIAGNOSIS

Detect the presence of misfire occurrence. (Revolution fluctuation method)

Monitoring Misfire which influences exhaust deterioration (1.5 times of FTP) and catalyst damage is made

obligatory by the law. Misfire affecting these two has two patterns below:

• Intermittent misfire (The same cylinder misfires in random, or different cylinders misfire in random.): FTP

1.5 times misfire

• Every time misfire (The same cylinder misfires every time.): FTP 1.5 times misfire, Catalyst damage mis-

fire

The following detecting methods are adopted for these detection.

1) Intermittent misfire: FTP 1.5 times misfire

• 180° Interval Difference Method

• 360° Interval Difference Method (whole range)

• 720° Interval Difference Method (3,000 rpm or more)

2) Misfire every time: FTP 1.5 times misfire, Catalyst damage misfire

• 360° Interval Difference Method

Diagnostic Trouble Code (DTC) Detecting Criteria

GENERAL DESCRIPTION

4. DIAGNOSTIC METHOD

When a misfire occurs, the engine speed will decrease and the crankshaft position speed will change. Cal-

culate the interval difference value (diagnostic value) from crankshaft position speed by the following formu-

la, and judge whether a misfire is occurring or not comparing the calculated result with judgment value. Count

the number of misfires, if the misfire ratio is higher during 1000 revs. or 200 revs., judge corresponding cyl-

inders as NG.

As shown in the following figure, pick a cylinder as the standard and name it omg 0. And the former crank-

shaft position speed is named omg 1, the second former crankshaft position speed is named omg 2, the third

is named omg 3, etc.

Diagnostic value calculation

(Calculate from angle speed) →

Misfire detection every single ignition

(Compare diagnostic value with judg-

ment value) →

by the law) (Compare number of misfire with judg-

ment value)

GENERAL DESCRIPTION

Pump supply pressure check

Perform the system function diagnosis with how much the pressure rises when the secondary air pump is

turned from OFF to ON.

Judge as NG if delivery pipe pressure does not rise though it should when the secondary air pump turns OFF

→ ON.

If the duration of time while the following conditions are met is longer than the time indicated, judge as NG.

Time Needed for Diagnosis: 4000 ms

Malfunction Indicator Light Illumination: Illuminates when malfunction occurs in 2 continuous driving cy-

cles.

Combination valve both closed pulse diagnosis

Perform open stuck diagnosis of both combination valves using delivery pipe pressure pulse when both com-

bination valves are closed. Determine which side of valves is stuck open by comparing secondary air flow

amount when RH combination valve is closed with that when LH combination valve is closed.

Calculate voltage pulse of the pump delivery pipe pressure when both combination valves are closed. The

calculation should be small because there is no pulse from supply pipe pressure with both combination

valves closed. When the calculation is large, determine that either of the combination valves is stuck open.

Determine which side of valves is stuck open by comparing secondary air flow amount when the RH combi-

nation valve is closed with that when the LH combination valve is closed. Air flow amount is larger on the

open stuck valve.

If the duration of time while the following conditions are met is longer than the time indicated, judge as NG.

Time Needed for Diagnosis: 992 ms + 992 ms + 992 ms + 4000 ms

Though the rear oxygen sensor output changes slowly with a new catalyst, the sensor output with a deteri-

orated catalyst becomes high and the inversion time is shortened.

For this reason, the catalyst diagnosis is carried out by monitoring the rear oxygen sensor output and com-

paring it with the front oxygen (A/F) sensor output.

CY:DTC P0455 EVAPORATIVE EMISSION SYSTEM LEAK DETECTED (LARGE

LEAK)

1. OUTLINE OF DIAGNOSIS

This diagnosis judges whether the ELCM operation is normal or not, and whether the evaporative emission

system has leak and clogging or not.

To purge the canister, after driving, perform the five hours soaking after ignition switch OFF in order to sta-

bilize the evaporative gas status. * After 5, 7 or 9.5 hours passed, ECM is activated by soaking timer, and the

leak check is started.

Judges whether the ELCM operation is normal or not, by measuring the reference pressure status via refer-

ence orifice (0.02 inch orifice). Judge as malfunction if the reference pressure is out of specified range. Then,

judge whether there is a leak or not, by comparing the pressure (leak pressure) when the reference pressure

and the evaporative emission system are in negative pressure condition. Judge as system leak in the evap-

orative emission system if the leak pressure is higher than reference pressure. Judge as clogging of pipe if

the leak pressure becomes lower than the reference pressure within the specified amount of time.

0.02 inch leak and 0.04 inch leak can be distinguished by measuring the leak pressure.

The diagnosis results are stored inside ECM until the engine is started again.

*: When the test conditions are not met in 5 hours, perform diagnosis at elapsed time of 7 hours. When the

test conditions are not met in 7 hours, perform diagnosis at elapsed time of 9.5 hours.

GENERAL DESCRIPTION

FP:DTC P219A BANK 1 AIR-FUEL RATIO IMBALANCE

1. OUTLINE OF DIAGNOSIS

This diagnostic monitor performs a functional check of the fuel system to determine an air-fuel ratio cylinder

imbalance.

This diagnosis is composed of two monitors.

The outline of “monitor A1” is as follows. When an air-fuel ratio cylinder imbalance occurs, the primary oxy-

gen sensor output signal will oscillate with increased amplitude. This monitor utilizes this behavior to make

a diagnosis. The monitor integrates the difference between the amplification value and the mean value of the

first oxygen sensor output signal and compares it to a threshold to make a judgment.

The outline of “monitor B1” is as follows. Similarly, when an imbalance occurs, the engine speed also fluctu-

ates with increased amplitude. This monitor utilizes this behavior to make a diagnosis. For reference, it

should be noted that this imbalance monitor method is actually similar to the current misfire diagnostic mon-

itor, and the parameter “domg360” (units: degrees CA) is shared between the imbalance and misfire moni-

tors. The imbalance monitor is performed during idle condition when the engine is warm. The monitor

integrates the count of “domg360” which exceeds a threshold in 1000 revolution.

When both the “monitor A1” value and the “monitor B1” value exceed a predetermined threshold, this monitor

determines a malfunction and stores a fault code.

Diagnostic Trouble Code (DTC) Detecting Criteria

GENERAL DESCRIPTION

Monitor A1

When there is an air-fuel ratio cylinder imbalance malfunction, the primary oxygen sensor output fluctuates

widely compared with a normal sensor, as shown by the chain line in Figure 1 below. This monitor makes a

diagnosis based on this phenomenon. Each primary oxygen sensor signal (PS) and mean value of the pri-

mary oxygen sensor signal (MS) is calculated from the primary oxygen sensor signal. The absolute values

of (PS – MS) are sampled every 4 ms as shown in the figure. Diagnostic value 1 (DV1) is obtained by inte-

grating the absolute value of (PS – MS) for 2500 times. A malfunction is determined when DV1 exceeds the

threshold. The judgment values are determined experimentally.

GENERAL DESCRIPTION

Monitor B1

Method used: Difference method of 360 degrees CA

Monitor value: domg360 = (omg 1 – omg 0) – (omg 3 – omg 2) = angular speed

Each crankshaft angular speed is defined as Figure 2 below.

Figure 2. Description of domg360 output

This method uses the fact that the domg360 of lean conditioned cylinder caused by imbalance malfunction

indicates big value, as shown by the chain line in Figure 3 below.

The number of times for domg360 to exceed the judgment value in 1000 revolutions (500 cycles) is calculat-

ed as diagnostic value 2 (DV2). A malfunction is determined when DV2 exceeds the threshold.
